Here is one Example: Example #1 AAAAABBBBBCCCCCDDDDD AAEBCBAFBBCDCECDADDEFEEFFF At first glance the sample looks significantly different after the second test. But if you look at the data, you will note that since we only care about A,B,C,D’s that the second line does have the same number of A’s , B’s, C’s and Ver 3.0 D’s. This means that while it looks different we would say that the sample is non-mutated. Note however that what is important is not the exact number, but the percentages. In the above case the percentages are 25% A’s , 25% B’s, 25% C’s and 25% D’s. (Note that it is 25% of the letters we care about, not the total). If another sample started with 10 A’s, 10 B’s, 10 C’s, and 5 D’s, and ended with 20/20/20/10. That would also be considered a nonmutation because while the numbers are different, the percentages are the same. Contrast that with the data below. Example #2 AAATAABTBBBBCCCCTCDDTDDD AASAABBSBBCCSCCDSDDDEEEAEEFBFFFDDF If we look at example #2. The initial percentages are [25, 25, 25, 25] but then in the second test they changed to [25, 25, 20, 30], which is a change and therefore counts as a mutation.

The Data.txt output file name? Results.txt PROGRAM NOTES Ver 3.0 You should round percentages to the nearest integer. You can use the Math.round method to do so, but you will have to cast the result to an int, as in: int percent = (int) Math.round(percentage); The output for this program will generate an output file. You do so by constructing an object of type PrintStream and writing to it in the same way you write to System.out (with print and println statements). See section 6.4 of the book for examples. It is a good idea to send your output to System.out while you are developing your program and send it to the output file only after you have thoroughly tested your program. You can read the user’s answers from the input file using a call on nextLine(). This will read an entire line of input and return it as a String

You should round percentages to the nearest integer. You can use the Math.round method to do so, but you will have to cast the result to an int, as in: int percent = (int) Math.round(percentage);

You do so by constructing an object of type PrintStream and writing to it in the same way you write to System.out (with print and println statements). See section 6.4 of the book for examples. It is a good idea to send your output to System.out while you are developing your program and send it to the output file only after you have thoroughly tested your program.
You can read the user’s answers from the input file using a call on nextLine(). This will read an entire line of input and return it as a String.
